In an exciting and quite successful first season the TU Graz e-Power Racing Team demonstrated without any doubt that the innovative electric technology is able to compete with traditional petrol-engined racing cars. The biggest challenge in our previous season was the integration of an electric drivetrain into an existing chassis. For the current season we concentrated on a perfect placement of all components in our new chassis, for which we used a complete different production process. All of the valuable experiences we gained last year influenced us a lot. Every component was analysed in terms of durability, efficiency and safety. Great value was placed on an advanced motor control to gain more power out of our batteries.
Our whole team is looking forward to a new great season. Especially the fact of the increasing number of teams, which are starting in Class 1A, promises an exciting Formula Student event
